Research On Measuring Benefits Of Using BIM For Owner

In recent years, International Building Information Modeling is one of the hot issues in the field of construction industry, but there are still a lot of limitations for BIM application in China because of unclear evaluation of BIM benefits. Owners play a leading role in the operation of a construction project and promotion of BIM. Therefore, it is of great significance to carry out in-depth studies and reviews on BIM value for owners, especially on BIM benefits.Aiming at the above problems, based on the concept of BIM benefits, firstly, this paper collected the existing research scholars about the benefits evaluation of BIM. And the paper made a statistical analysis of the papers, including distribution of publication year, study methods, indicators of benefits, getting correlative conclusions that different parties concern in different BIM benefits in different stages, and organizing the indicators of BIM benefits. Then combined with characteristics of BIM application for owners and correlative conclusions from the statistical ananlysis, the system of BIM benefit evaluation for owner in differnent stage was built. What is more, the evaluation criterias setted by business evaluation theory. Secondly, on the basis of concepy of BIM investment efficiency, the indicators of BIM investment efficiency was built. And quantitative evaluation of BIM investment efficiency for owners by data envelopment analysis(DEA) was carried out. Finally, taked International Conference Center as example, actual situation of BIM application and application results was introduced in detail. The conclusion of significant benefits and effectiveness investment efficiency of BIM was obtained by measuring the benefit of BIM in design stage and investment efficiency for owners.Through the research on BIM benefits for owners, the value of BIM is introduced and owners have a more profound understanding of BIM, which hope to provide a positive impact on the application of BIM.
